Meconium peritonitis secondary to torsion of fallopian tube cyst and transient central diabetes insipidus in a preterm infant.

Meconium peritonitis is a sterile chemical peritonitis caused by peritoneal seeding of meconium from an antenatal gastrointestinal perforation. We report a 32-week preterm female neonate who developed meconium peritonitis due to bowel perforation, secondary to a twisted left fallopian tube mass, which was excised and confirmed by histopathology. This association has not been reported earlier. The infant also developed transient central diabetes insipidus, a very rare condition in a preterm neonate.
